Tokunai not only allowed Siebold to copy sensitive maps of disputed territories in Northern Japan, but also donated him a set of 45 Japanese wood samples, most of them decorated with paintings of the foliage of the trees from which the wood came, and later provided with interesting notes on their timber uses by the Ainu people in “Jezo” (or Ezo-chi, more or less equivalent with modern Hokkaido). Based mainly on earlier detailed studies by Prof. Takao Yamaguchi and Prof. Nobushige Kato, we will discuss this collection in the context of contemporary and later wood collections and its significance for forest products research in and beyond Japan. Other Japanese wood collections taken to the Netherlands by Siebold were used for the very first Ph.D. studies on wood anatomy in Leiden, and possibly also in Munich. Siebold’s most important disciple Ito Keisuke (or Ito “Keiske”, or “Keisuke Itoh”, 1803–1901) oversaw the decoration of a set of painted wood samples for teaching purposes in Tokyo in the 1880s. From the 1870s onwards, Japan was actively promoting its timber resources at World Expositions in Vienna, Philadelphia, and Paris. In the latter two venues with another special type of wood collection: sections mounted on the pages of a book, possibly inspired by a concept developed by the German forestry scientist Hermann Nördlinger.

INTRODUCTION Wood collections are known from 17th Century Europe when they formed part of Curiosity and Naturalia Cabinets. Collec- tions of medicinal plants and other simplicia often also contained wood specimens (Baas 1981; Feuchter-Schawelka et al. 2001; Cornish et al. 2014). This study focuses on an early and unique collection of wood samples from Japan, decorated with hand- painted branches and leaves of the species involved, and preserved in the collections of the Naturalis Biodiversity Center in Leiden, The Netherlands. Earlier studies on this collection are by Baas (1981), Omori (1982), Tanisawa (1983), Ishiyama (1988), and above all by Yamaguchi & Kato (1998) who fully documented it in their series of publications on Siebold’s botanical collections in special issues of the Bulletin of the Aitsu Marine Station, Kumamato University, Japan: Calanus. This paper is largely based on Yamaguchi & Kato’s publication, and dedicated to the memory of Professor Takao Yamaguchi (1937–2013; for a biography see Baba 2013) who visited Leiden 44 times to study the natural history collections made by Siebold, including the Tokunai Wood Collections. Apart from a summarized description of the Tokunai collection, we will discuss its relevance from ethnobotanical and wood utilization points of view and explore possible links with later 19th-century wood collections made in Japan for public education, research, and trading purposes. © International Association of Wood Anatomists, 2021 DOI 10.1163/22941932-bja10057 Published by Koninklijke Brill NV, Leiden 2 IAWA Journal 0 (0), 2021 Figures 1–3.

The decorated Tokunai wood collection In 1826 when Philipp Franz von Siebold (Fig. 1) took part in the so-called Hofreis (Court Journey) of the Dutch delegation from Deshima in the bay of Nagasaki to Edo, present-day Tokyo, he met an old and wise scientist, Mogami Tokunai (1755– 1836; Fig. 2). Siebold’s entry in his diary of 16 April devotes a couple of lines in Latin to this meeting. He bursts out “Dies sane calculo candidissimo notandus” — Definitely a brilliant day — “A Japanese named Mogami Tokunai showed his great ability in mathematics and related sciences. We discussed on Chinese, Japanese, and European Mathematics. Then he showed me, under the seal of secrecy, maps of oceans surrounding Jezo (or Ezo-chi, more or less equivalent with Hokkaido), and Karafto which is in dispute (= Karafuto, current Sakhalin, Russian territory since 1945). He kindly permitted me to use the maps for a while. What a great treasure”. Geographical maps were a state secret in Japan, and Yamaguchi & Kato (1998) speculated that Baas et al. – Tokunai’s wood collection 3 because Siebold realised this, he changed in his diary from German (not dissimilar to Dutch — in those days “the Latin of Japan”, which a number of Japanese officials could perfectly read and understand) to real Latin which they could not. During the following four weeks, Siebold and Tokunai were more or less in daily contact, and despite the fact that Siebold was extremely busy exchanging medical expertise and biological and ethnographical information with many Japanese col- leagues (Siebold 1858; Oijen & Oijen 2005) he seems to have cherished the meetings with Tokunai enormously because in his later years Siebold would often refer to his old and wise friend Mogami Tokunai (or Toknai). During one of these encoun- ters Tokunai presented Siebold with a collection of 45 wood samples, mostly — but not all — from Jezo = Ezo-chi, mainly present-day Hokkaido, then the region of Northern Japan inhabited by Ainu people, now an endangered ethnic group, for whom Siebold showed a great ethnographic interest. The Ainu language, which did not have a script, differs from Japanese despite some similarities but is very different from Chinese. Tokunai had produced a draft Japanese-Ainu dictionary and Siebold must have picked Tokunai’s brain feverishly during the few weeks of their encounter — posthumously even resulting in an Ainu-German dictionary published in Vienna by A. Pfizmaier (Yamaguchi & Kato 1998). That dictionary also includes the plant names written in Chinese and Japanese script on the wood samples by Mogami Tokunai himself. What makes the wood samples unique is that Tokunai painted the leaves of the trees from which the samples came on them (Yamaguchi & Kato 1998). Tokunai also calligraphed the Ainu and Japanese names on the samples, and their uses on some of them. On the reverse side, most samples contain notes on the traditional uses by the Ainu people; most of them in German by Siebold himself, while others have labels in a different hand in Dutch (sometimes with linguistic mistakes) pre- sumably by Japanese pupils or assistants. In later life Siebold incorporated these notes in his most important publications: (1) Nippon (Siebold 1858) and (2) Flora Japonica (Siebold & Zuccarini 1835–1870), plus miscellaneous published and unpublished reports on Jezo and the Ainu culture. In 1830, together with many other collections, the 45 wood samples were sent by Siebold to the Rijksherbarium, then just founded in Brussels, in one of the two crates of which the contents were to be hotly contested between herbarium director C.L. Blume and the Dutch Government on the one hand, and Siebold on the other, as to whether they belonged to Siebold or the Dutch State (Yamaguchi 1997; Thijsse 2005; Compton & Thijsse 2013). Tokunai’s collections lived an obscure life in the Rijksherbarium until the mid-1900s when the then director decided that wood collections did not really belong in a Herbarium, and donated them to the Department of Botany of Leiden University. There they sat among the teaching collections in the room where student demonstrators of the practical courses in plant anatomy would prepare their classes. In 1969 one of us (PB) had been appointed in a double function as a researcher of systematic wood anatomy at the Rijksherbarium, whilst carrying out teaching duties in the Department of Botany. Nobody knew where the highly decorative wood collection (Fig. 3) came from or what its significance was. At the Rijksherbarium, it’s then-director C.G.G.J.
